Absolutely no interest in the Lammy stuff, but genuinely - what makes you think this is a great idea? Do you think *anyone* who carries a knife is gonna look at a chicken box and go 'actually yeah, ill change now'? They've all most likely had police, friends, family and more preaching to them at some point to not get into trouble. Why would this have even 1% of the impact of that... really don't get it.
They've actually been doing it for ages, and it's obviously not had any impact no violence levels. They just chose to announce it yesterday for some unfathomable reason.
